摘要:
A digital-to-analog converter including a resistor string configured to provide a plurality of gradation voltages formed by receiving a top voltage at one end thereof and a bottom voltage at the other end; a plurality of pass transistors including a pass transistor having one end which is electrically connected to the resistor string and outputting any one among the plurality of gradation voltages; and a decoder configured to control the plurality of pass transistors. The plurality of the pass transistors are included in any one among a plurality of groups according to values of the gradation voltages, and the pass transistors included in the any one group are divided into a first group and a second group according to output gradation voltages, and pass transistors included in the first group and pass transistors included in the second group are different types of pass transistors.
